Without much fanfare, or even an official announcement, it appears that Google has extended its official Play Store refund policy from an unreasonable 15 minutes to a fairer two hours.
According to Google’s official support documentation:
After purchasing an app or game on Google Play, you can return it within two hours for a full refund.
If the two-hour return period has passed, we recommend contacting the app developer directly. You can find an app developer’s contact information listed on an app or game’s detail page on Google Play.
In order to return an app, simply open the Google Play Store, select My Apps, find the app you’d like to return, and tap Refund. Within the two-hour time frame, you will see options to either open or refund the app, but after two hours have passed, the refund option will into an uninstall button.
Also important to remember is that you can only refund an app once: If you decide to purchase it again later, it’s yours.
I’m not quite sure when Google changed it’s policy, but the company seems to be on a consumer-friendly kick lately.[Google]
